Resurrecting The Resurrected…
A while ago I read an article at http://thomasstock.com/NIKG 'Resurrecting the Kieseritzky' by Michael A. Jensen. In the article he analyzes a new idea in the Berlin defence aimed against white's new set-up with Be2. Compared with the main variation 9…Qe7, Black gains a tempo if white tries to escape the pin on the e-file with 0-0 since now Qd8xh4 will be lethal. Jensen's conclusion is that 6.d4 should be abandoned for 6.Bc4…
Since I don't like the positions arising from 6.Bc4 I tried to find a hole in the analysis, but wasn't very successful (at one extreme time of desperation I even took a look at 6.Bb5? - in a vain attempt to fight for e5…).
Finally, I had a look in the database and saw the light in the end of the tunnel. I present my findings here, as a helping hand to other desperate readers…
